Regulator – MK11 EVO/S270

The SCUBAPRO MK11 EVO / S270 is a reliable and easy-to-use regulator system designed for divers who want consistent performance without unnecessary complexity. Combining the balanced diaphragm MK11 EVO first stage with the compact and lightweight S270 second stage, this system delivers effortless airflow across a wide range of depths, tank pressures, and breathing rates.

The MK11 EVO first stage features a compact, air-balanced diaphragm design that ensures smooth and stable air delivery, unaffected by depth or supply pressure. Its forged chrome-plated brass body includes integrated metal fins that improve thermal exchange for enhanced cold-water performance, while protective plastic bumpers help prevent scratches and extend service life. An innovative double-spring layout boosts performance while keeping the regulator compact and travel-friendly.

With two angled high-pressure ports and four high-flow low-pressure ports, the MK11 EVO offers excellent hose routing flexibility for a wide variety of recreational configurations. It is CE certified to EN250A standards, making it suitable for warm, temperate, and cold-water diving, including extreme conditions.

The S270 second stage delivers smooth, reliable breathing in a lightweight, anti-scratch casing built for years of use. Its fiberglass-reinforced nylon core and protective PU outer layer reduce weight and help minimize jaw fatigue during longer dives. The balanced valve design ensures consistent inhalation effort at varying depths and tank pressures, while the efficient exhaust tee minimizes exhalation resistance for greater overall comfort.

Designed with practicality in mind, the dive/pre-dive switch is easy to operate—even with thick gloves—helping prevent freeflows at the surface while ensuring optimal airflow underwater.
